An Architectural Estate Designed for Elevated Living! Privately set on over 2 pristine acres within the coveted Grey Cliffe Estates, this exceptional contemporary estate offers a rare blend of architectural sophistication, resort-style amenities, and natural serenity. Set well back from the road behind a mature vegetation buffer, the home is approached by a long, winding driveway with a circular motor court, creating an immediate sense of privacy, presence, and arrival. Bordering a tranquil shared pond, the property uniquely includes private sandy beach access, offering a true four-season lifestyle-ideal for kayaking, canoeing, fishing, ice skating, or simply enjoying peaceful water views. Professionally landscaped grounds feature an irrigation system and timed landscape lighting, enhancing the park-like setting and complementing the surrounding luxury estates. Spanning approximately 8,708 square feet with nearly 6,000 square feet above grade, the residence showcases dramatic ceiling heights, expansive sightlines, and walls of glass throughout. A desirable southern rear exposure fills the home with natural light, creating an open yet warm living environment that balances architectural impact with everyday comfort. The architectural centerpiece is the breathtaking two-story great room, featuring soaring ceilings, a gas fireplace, custom built-ins, and a striking 240-gallon saltwater aquarium integrated as a living work of art. This space flows seamlessly into the chef's kitchen, appointed with extensive white cabinetry, generous counter space, a substantial center island with Thermador cooktop, double ovens, Sub-Zero refrigerator/freezer, and breakfast bar seating. A sunlit breakfast area offers backyard views and access to the covered patio, while a separate formal dining room provides an elegant setting for entertaining. An atrium-style family room with a full wall and ceiling of glass creates a dramatic indoor-outdoor connection rarely found. The first-floor primary suite is a private retreat featuring custom walk-in closets and a spa-inspired bath with dual vanities, soaking tub, and full-body glass and tile shower. A first-floor office with custom built-ins and an updated powder room complete the main level. The second floor features a glass-railed gallery overlooking the living space below, spacious secondary bedrooms including a Jack-and-Jill arrangement, and an additional en-suite bedroom. A separate second-floor wellness retreat, accessed by its own stairwell, includes heated floors, steam room and shower, sauna, full bath, bonus room ideal for yoga or meditation, and a sitting area-perfect for wellness-focused living. The finished lookout basement is designed as an extension of the home's entertaining and lifestyle spaces, offering a sprawling recreation area ideal for gatherings, game nights, or casual lounging. A private theater room creates an immersive viewing experience, while the wet bar, fitness room, fifth bedroom, and full bath provide comfort and versatility for guests. A temperature-controlled wine cellar and generous storage complete the lower level. Additional highlights include an oversized heated 5-car garage, large mudroom and laundry area, plantation shutters, multiple zoned HVAC systems, whole-house generator, reverse osmosis water system, integrated security system, and whole-home audio.
